The product is a unique Eschle automated bird cage from West Germany, featuring a jeweled cage. The bird will move if you wind-up the movement and blow into the hole (with the switch) to get the wheel inside to spin. I have disassembled and oiled with clock oil, but believe the attempts to glue patch the bellows (what makes the bird sounds) and this stiffening of the bellows folds added resistance to the movement. Once the wheel spins it will continue to spin until the mainspring runs out. I chose to leave the bellows repair to the new owner. There are many YouTube videos on doing this work. This decorative collectible is a rare find and showcases the craftsmanship of German artisans, making it a valuable addition to any music box collection.
